Did the error message Error message IEC070I 034(004), Please control.If Error message IEC070I 034(004) has NOT been issued, please open a case to CA Support.If Error message IEC070I 034(004) has been issued, you reached the 4gb limit for a standard VSAM (non-extended vsam datasets).

The error IEC070I 034 indicates that the maximum relative byte address (RBA) limit (4,294,967,295) has been reached and the return code 004 indicates the end of volume for a non-extended VSAM file.The solution is to convert KSDS to Extended Addressability.But as Extended Addressability XAADDR option is only available for SMS sites, it must be implemented in the ACS routines and/or by specifying an appropriate DATACLAS. Then you need the assistance from your DFSMS Storage folks to have such DATACLAS created and other SMS definition such as MGMTCLAS.To solve case, follows these steps:1. Know the MGMTCLAS and DATACLAS for Extended Addressability2. Convert the KSDS21. REPRO the current MCF files out to sequential DS.22. DELETE and REDEFINE the MCF under an SMS data class for extended format.23. REPRO the SEQUENTIAL file back into the new VSAM MCF files.

The sample job BC1JRMCF from the Endevor JCL library 'UPRFX.UQUAL.CSIQJCL' can be tailored to do the copy and the allocation of the files with the SMS parameters for the extended format.
